W'ILHELllI MATT, OF NEXV YORK, N. Y., ASSIGNOR TO THE PATENT MARBLEVENEER COMPANY, OF SAME PLACE.

ARTIFICIAL STONE FOR VENEERS, MOLDED ARTICLES, 86C.

srncrrrcnrron forming part bf Letters Patent No. 289,112, dated November27, 1883.-

Application filed May 11, 1883. (No specimens.)

, To all whom it may concern.-

same.

.My invention relates to a new composition of matter for use as a eneeror artificial surface for wood, plaster, papier-mach, ceramics, 82c, andthe same is an improvement upon with the mass of glue.

the composition described in Letters Patent No. 266,493, granted to meOctober 24, 1882.

The composition composing the subject of my invention is best made inthe following manner: Take, say, ten pounds of copperglue, and soak thesame in about eighteen pounds of water, and then completely dissolve theglue by boiling with overheated steam. During the boiling I add to thissolution of hot glue about ten pounds of fine asbestus and thoroughlystir" and mix the fibers of the same In the meantime I take aboutone-halfa pound of boiled linseedoil varnish and one-half pound ofcolophony and melt them together, andwhile in a boiling condition addthem slowly to the aforesaid hot solution of glue and asbestos, and Ikeep the mass in a constant state of agitation by stirring until no morefoam or air-bubbles appear. To the hot mass I now add about one U poundof glycerine and stir as before, and I compound may be colored by theaddition of v such pigments as taste or fancy may dictate. The plasticcompound thus produced is made ready for use as a veneer by being rolledout into thin sheets, which are united to the surface to be covered bycoating=- both the sheet of composition and the surface to be veneei edeachwith a film of hot glue, in thin solution, and then pressing the twotogether, as in the ordinary process of veneering wood. In this mannernot only all manner of wood surfaces may be veneered with the compound;but it may be applied to plastertwalls, to papiermach, and in fact toall surfaces to which the glue will adhere. The composition will hardenwithin twenty-four hours and become as hard as stone, and presents asmooth finished surface, which admits of receiving a veryhigh polish.This polish may be produced by first rubbing down with pumice-stone andoil of turpentine and finishing with sandarac-polish in the usualmanner. When applied to a wooden surface, this composition adheres soclosely as to become apparently an integral part therewith, and it is sohard that it will not break or peel 0E, but will in some cases 6 be moredurable than the body of the article, the combination of the glue andthe glycerine in the compound making it both tough and elastic.

For producingan imitation of marble with this compound, I take suitablecolors and mix separately with each a proportion of finelypulverizedsteatite or kaolin, each color being placed in a separate heap uponamarble slab. The center of each heap is hollowed outto receive aquantity of the hot fluid solution of glue, asbest-us, linseed-oilvarnish, colophony, glycerine, and turpentine sufficient to reduce themass to a pasty condition. hen the several colors are thus made ready,each in the form of paste of proper consistency, they are kept ready foruse by enfoldin g them in a damp cloth. When required for use, theseparate masses of color are steamed until heated through and throughand fully softened, and are placed upon the marble slabs in rolls, whichare properly laid together and interfolded, rolled out with a suitablemetallic roller, folded, and again rolled into athin sheet, whichwillfinally become veined in a beautiful 0 imitation of marble.

The proportion of the several ingredients herein named are those bestadapted to produce the desired results. They may, however, be slightly'varied without departing 5 from my invention.

I claim as my invention- 1. A composition of matter for veneering ormolding purposes, produced by an admixture, in substantially theproportions and manposed of glue, asbestus, 1inseed;oi1 varnish,colophony, glycerine, and turpentine, as set-15 forth.

4. The composition herein specified, composed of glue, asbestus,1inseed-oi1 varnish, colophony, glycerine, turpentine, steatite orkaolin, and coloring-pigments, as set forth. 2o
